Simply Xtreme Tyre Inflator Sealer provides you with an instant tyre repair without the need to even remove the wheel. It works deep inside the tyre to form a special sealing film which ensures an effective repair. The foam seals the puncture and inflates the flat tyre. You can drive immediately after filling the tyre. Check the tyre pressure as soon as possible at a service station. Deflate the tyre and then inflate to correct pressure. Xtreme Tyre Inflator and Sealer will not damage your tyre or wheel if applied correctly. It will not affect tyre tracking or alignment.
